All England Open: Sindhu suffers first-round exit; Gayatri-Treesa pair advances to Round 2

Sindhu, ranked ninth in the world, lost to the world No.17 Chinese shuttler 17-21, 11-21 for her third first-round exit of the year. The former world champion also crashed out early from the Malaysia Open and India Open earlier this year.

Playing against the drift, the Indian ace started with a measured approach and held a lead at 16-13. However, Zhang's cross-court smashes helped to claw her way back into the match and sealed the opening game 21-17.

After the change of sides, Sindhu seemed to struggle to lift her game as Zhang Yi Man opened a four-point lead at the time of the mid-game break and built on it to seal the match in 39 minutes.

Earlier in the day, teenage women's doubles pair of Treesa Jolly and Gayatri Gopichand, who got a major breakthrough in their career in the last edition as they entered the semifinal after being promoted from the reserves, got off to a winning start and paved a way to the second round.

Treesa and Gaytari registered a 21-18, 21-14 straight games victory against seventh seeds Thai pair Jongkolphan Kititharakul and Rawinda Prajongjai. This was the Indians' first win over the Thai pair in five meetings.

The Indian duo, who reached the semifinal last year, will be up against the winner of the match between the Scottish pair of Julie Macpherson iamp; Ciara Torrance and Japan's Yuki Fukushima iamp; Sayaka Hirota on Thursday.
